TPS26631RGER

Current Regulation/Management Overview

The TPS26631RGER is a single-channel electronic fuse (eFuse) from the Texas Instruments TPS2663 family, designed for industrial power distribution. It integrates a 60 V, 31 mΩ N-channel FET and supports input voltages from 4.5 V to 60 V with a maximum continuous output current of 6 A. The device features adjustable current limiting (0.6 A to 6 A), programmable output slew rate control, and overvoltage protection. It includes an external B-FET driver for reverse polarity and reverse current blocking. Key specifications include ±2% accuracy on current limit settings and operation across a junction temperature range of -40°C to 125°C.

Current Regulation/Management Feature Summary

• Integrated 60 V, 31 mΩ power FET with adjustable current limiting and output power limiting capabilities
• External B-FET driver supporting reverse polarity protection and fast reverse current blocking
• Programmable output voltage slew rate control to manage inrush currents during system power-up
• Configurable fault response modes including latch-off and auto-retry via the MODE pin

Current Regulation/Management Applications

• Industrial hot-swap and power rail protection systems
• PLC, DCS, HMI, and I/O module power distribution
• IEC 61000-4-5 industrial surge protection applications
• Motor drive and CNC equipment power management

Current Regulation/Management Procurement Notes

Verify the specific suffix 'RGER' corresponds to the 24-VQFN (4x4) package and Tape & Reel packaging format. Confirm that the component meets RoHS3 compliance and REACH standards as specified by Texas Instruments. Ensure the design accounts for the exposed pad thermal requirements associated with the VFQFN package type for proper heat dissipation.

Current Regulation/Management Selection Notes

Select this component when a single-channel eFuse with high voltage tolerance up to 60 V is required. It is suitable for designs needing precise current regulation with ±2% accuracy and integrated surge protection capabilities. Consider the external B-FET driver feature if reverse current blocking or enhanced reverse polarity protection is necessary for the application architecture.

Current Regulation/Management Part Context

This part belongs to the TPS2663 series of power-limiting, surge-protected industrial eFuses. The series provides a unified platform for protecting downstream loads against overcurrent, short circuits, and thermal events. The TPS26631 variant specifically offers standard current limiting without additional advanced diagnostic features found in other sub-models within the same family.

Current Regulation/Management Replacement Considerations

Compatible substitutes within the same family include TPS26630RGER, TPS26632RGER, and TPS26633RGER. These parts share similar electrical characteristics but may differ in specific diagnostic outputs or current limit configurations. Verify pinout compatibility and functional equivalence before substitution.
